Baking path animation deletes poses?
Ok, I basically messed around with it until I figured out that selecting the 'Pose' option in the bake settings only works if you have a bone selected in pose mode, so I just selected all my bones in pose mode, chose 'Pose' and 'Object' in the bake settings, deleted the path, and now it works. Thanks to @joshsanfelici for giving me the idea to check edit mode, which made me think of selecting the bones.
